PPGI & PPGL Sheet Coating
The total thickness of the pre-painted galvalume steel coil is composed of the base steel – coating -primer – top paint – protective layer thickness. The top paint thickness is 10-25μm, and the back paint thickness is 5-20μm. The thinner the base steel thickness, the higher the price of the ppgi steel coil, because the processing cost becomes higher.


Product information
Usually the paint coating material is polyester (PE) and the color of the back paint is white grey. The color can be customized according to the RAL color card or customer samples. Special patterns can be made, such as wood grain, flower print, camouflage, brick.

PPGI Production Process Flow Chart

Unrolling → Stitching machine → Entrance loop → Pretreatment → Initial coating → Bake → Cool down → Fine coating → Bake → Embossed film → Export loop → Inspection station → Cut → Coiling
In the above process, if the cleaning degreasing process is not handled well, the adhesion of the primer of the color coated plate to the galvanized sheet is not good, and it is easy to cause the top coat of the color coated steel coil to fall off during the press forming process.
Coating primerTop paint coating
1)  Epoxy primer, good adhesion, water resistance, alkali resistance, chemical corrosion resistance, poor single toughness.
2)  Polyester primer, good adhesion, good flexibility, sensitive to humid environment, chemical resistance is not as good as epoxy primer.
3)  Acrylic primer, good adhesion, good toughness and high pretreatment requirements.
4)  polyurethane primer, chemical resistance, abrasion resistance, durability, toughness
1)  Polyester resin, good adhesion, molding and outdoor durability.
2)  Silicon Modified Polyester (SMP)
3)  High weather resistant polyester (HDP)
4)  Polyvinyl fluoride (PVC)
5)  Polyvinylidene fluoride/fluorocarbon (PVDF) It has good formability and color retention, good outdoor durability and powder resistance, solvent resistance, limited color and high price.


Color Coated Steel Feature Excellent Decorativeness, Bendability, Corrosion Resistance, Coating Adhesion And Color Fastness.They Are Ideal Substitutes For Wood Panels In The Construction Industry Because Of Their Good Economic Features Such As Convenient Installation, Conservation Of Energy And Resistance To Contamination. Color Steel Sheets With Surface Texturing On The Surface Has Extremely Superb Anti-Scratch Qualities.Can Be Produced In Various Colors, And Has Credible Quality And Can Be Mass-Produced Economically.

About us

Founded in 2014, Jiyue Steel Co., Ltd. initially focused on providing high-quality steel for the rapid development of China's infrastructure. Based on the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel products in the international market, the company started its international business in 2016 and successfully passed the ISo9001:2008 quality management system certification.

With high quality steel products and professional services, Jiyue has won international praise in infrastructure, shipbuilding, petroleum and other industries, and gradually grew into a shining star in the steel export industry. With the exploration and innovation of the company, gradually formed the advantages of steel plate products, and established its own machining center, in order to meet the diversified requirements of customers.

Packaging & shipping

Packaging and loading:

Packaging: According to customers' needs, use wrapping paper. If the transportation period exceeds 10 days or encounters special climate, we will use waterproof packaging and add plastic film to prevent moisture, water and rust.

Loading: We use the wooden pallet,triangular wood to fix the coil,and the steel wire rope to hold on the both side. That can prevent from the crush injury effectively.
